Analysis of slow depolarizing potential in frog taste cell induced by parasympathetic efferent stimulation under hypoxia.

abstract：:The adult olfactory system undergoes experience-dependent plasticity to adapt to the olfactory environment. This plasticity may be accompanied by perceptual changes, including improved olfactory discrimination. Here, we assessed experience-dependent changes in the perception of a homologous aldehyde pair by testing mi...
